Concept Pic of Yellowjacket from Ant-Man
The Ant-Man teaser trailer didn't show us much (not that I was expecting it to) but the biggest reason why I'm not worried because of things I know we haven't seen yet. Like the live-action version of this Yellowjacket costume:
The Ant-Man suit itself looks great and so I expect the live-action version of this concept art to loo pretty close to the real thing. It will probably be a while before we see that but, I'm definitely interested in seeing how this plays out. I think if anyone can do it, Marvel Studios can.
